Answer:
F1 = k Q1 * Q2 / R^2
If Q1 is doubled then F2 = 2 F1 = 72 units
4.22
Explanation:
The most acidic rainfall in New York State will have pH of 4.22 whereas the least acidic will be that of 4.40.
The pH scale expresses the acidity or alkalinity of aqueous solutions.
- The pH scale ranges from 1 to 4
- An acidic solution will have a pH value less than 7
We have given a range of values between 4.22 to 4.40
This implies that the pH values of rainfall in this region falls between these extremes.
The least value 4.22 is the most acidic
The value 4.4 is the the least acidic
The lower the pH value, the more acidic a solution is.
